The diameter of the pan is 9 inches. What is the approximate circumference of a lid that will fit his frying pan? (Use 3.14 for .)

Answer 1

Do you know the equation for the circumference of a circle?

Answer 2

I think it is 9 x 3.14

Answer 3

or 9 divides 3.14

Answer 4

\(2\pi r^2\) or \(\pi d\)

So you would be correct yeah.

Answer 5

So what would the answer of \(2\pi (4.5)^2\) or \(\pi (9)\) be?

Answer 6

Correction* \(2\pi r\).
